What is the network portion of 177.100.18.4?
In the IP address 177.100.18.4, the network portion is determined by the subnet mask. Without knowing the subnet mask, it is impossible to accurately determine the network portion. The network portion is used to identify the specific network to which the IP address belongs, helping in routing and communication between devices.
network portion of these addresses: 209.240.80.78?
This is a class C address. The network portion is the first three octets, so it would be 209.240.80.0.
How do you know how many bits represent the network portion and the host portion?
When we express an IPv4 network address, we add a prefix length to the network address. The prefix length is the number of bits in the address that gives us the network portion. For example, in 172.16.4.0 /24, the /24 is the prefix length - it tells us that the first 24 bits are the network address. This leaves the remaining 8 bits, the last octet, as the host portion.
What is the first half a MAC address known as?
The first half of a MAC address is known as the Organizationally Unique Identifier (OUI). This portion consists of the first 24 bits and identifies the manufacturer or organization that produced the network interface hardware. The remaining 24 bits of the MAC address are assigned by the manufacturer to uniquely identify the specific device. Together, the OUI and the device-specific portion create a unique identifier for each network interface.
What portion of the IP address 129.219.51.18 represents the network?
It is a class B address (The first three numbers (octet) are between 128 and 191), meaning it has a subnet of 255.255.0.0, thus, 129.219 is the network portion, with 51.18 representing the host portion.
What is network id host id?
Network IDA network ID refers to a part of a TCP/IP address that is used to identify the subnet that a host may be on. The subnet that the computer is on is determined by the netmask and IP address of the computer. This subnet address is the same as the network ID and is the beginning part of the computers IP address.When the netmask is setup, it is a number where some of the most significant bits have a 1's value and the rest have values of 0. The most significant part of the netmask with bits set to 1's specifies the network address, and the lower part of the address will specify the host address.The part of the IP address that matches the part of the netmask where the bits are set to ones determines the network ID.
How long is the oui portion of a mac address?
The Institute of Electrical and Electronics Engineers (IEEE) designated by the International Standards Organization (ISO) as the registering body for OUI, which is utilized in the first 3 octets of a MAC address to identify the manufacturer of a network enabled device.
What is IP prefix?
an IP address is represented as A.B.C.D /n, where "/n" is called the IP prefix or network prefix. The IP prefix identifies the number of significant bits used to identify a network. For example, 192.9.205.22 /18 means, the first 18 bits are used to represent the network and the remaining 14 bits are used to identify hosts.
What binary bit is used in sub net mask is part of the network?
In a subnet mask, the bits that are set to '1' represent the network portion of the IP address, while the bits set to '0' represent the host portion. For example, in the subnet mask 255.255.255.0 (or /24), the first 24 bits are '1's, indicating that these bits are used to identify the network. Consequently, the remaining 8 bits, which are '0's, can be used for hosts within that network.
What is the broadcast address for 136.78.113.75 255.255.244.0?
To find the broadcast address for the IP address 136.78.113.75 with the subnet mask 255.255.244.0, first convert the subnet mask to binary: 11111111.11111111.11111100.00000000. This means the first 22 bits are for the network. When you apply this mask to the IP address, the network portion is 136.78.112.0. The broadcast address, which has all host bits set to 1, is 136.78.115.255.
How does the IP address indicate the network?
The first octet determines what class of network you are located on. From that, you can determine how many of the octets represent the network address, and which part represents the client or host portion. IP addresses in version 4 (iPv4) are divided into two segments: the network id and the host id. Knowing the range of network class addresses will help: Class A is 0 - 126 and uses only the first octet for the network portion Class B is 128 - 191 and uses the first two octets for the network id Class C is 192 - 223 and uses the first three octets for the network id An example would be: 192.168.1.5 is a class C address, so we use the first three octets for the network id. This gives a network id of 192.168.1.0 and a host id of 5 in that network.
What constitutesthe serial number portion of the MAC address?
The serial number portion of a MAC address is typically represented by the last three bytes (24 bits) of the address. In a standard MAC address, which is usually formatted as six groups of two hexadecimal digits (e.g., 00:1A:2B:3C:4D:5E), the first three bytes (the Organizationally Unique Identifier or OUI) identify the manufacturer, while the last three bytes serve as a unique identifier assigned by the manufacturer to each network interface card (NIC). This ensures that each device has a unique MAC address within its network.
